H. The rim is shown provided with radially- The guard is attached to the casing by its 5 projecting buckets ab, between which are open rear edge and projects forward between the spaces 0 in the side of the wheel, to receive a wheel and the chamber 1 to the point where jet of water,-d, from a nozzle, 0. the water leaves the wheel, as shown in Fig.

The casing is shown enlarged or widened 5, the guard extending radially over the side near its base, to form a chamber, 1, to receive of the wheel enough to cover the buckets and to protect the same from the splash of the water after it enters the chamber.

From the chamber I the Water flows downward to the outlet K, finding a free vent past the vertical edge of .the guard, and also escaping past its bottom edge when the latter is not extended to the bottom of the casing, as shown in the drawings at Figs. 3 and 4.

As the water is discharged from the wheel wholly upon one side, it is obvious that the chamber l may be limited exclusively to one side of the casing, asin Figs. 1 and 2, a socket, F,'being provided upon the opposite side of the casing to admit the jet of the water ob- I liquely to the buckets a b, and the casing being widened only at 1 opposite to the point lettered 1A in Fig. 1, so as to form the body ofthe chamber I upon the opposite side of the casing. t

The enlargement I for the chamber I may thus be confined not only to one side of the casing, but also to one edge of the same as re garded from a straight line,m m, drawn through the shaft of the wheel and the discharge-outlet K. The rim of the wheeland its shaft are indicated in Fig. 2 by dotted lines a and E, and the guard .I is similarlyrepresented by dotted lines between the rim of the wheel and the chamber I.

It will be noticed that in Fig. 1 the casing is formed concentric with and close to the rim of the wheel on one side all theway to the point A, where itintersects the outlet K upon the side opposite the nozzlee, and that the casing is enlarged radially'only upon the side where the nozzle is inserted, such radial enlargement A being thereby restricted to one side only of the axial line at m.

To make the casing symmetrical,and to thus facilitate the process of manufacture by forming its two halves alike, the casing may be made, as shown in Figs. 3, 4, and 5, with a chamber, 1, opposite to that which is'required to receive the waste water; but such chamber is only essential uponone side of the whee1,to admit the use of a guard andvto furnish a free discharge of the water from beyond the same.

The water-nozzle in Fig. 5 is shown provided with a shank, e, secured movably within a boss, f, upon the end of the chamber I, and

the nozzle is slightly inclined to its shank, so that by turning the latter in the boss the direction of the jet in relation to the edges of the buckets may be slightly varied.

A dotted line is drawn through the center of the nozzle, and also through the center of its shank,to illustrate such inclination, the rotation of the nozzle entirely around in the boss thus serving to direct the jet into a variety of positions, all inclined at the same angle at the axis of the shank, but pointing upward or downward, inward or outward, froin the edges of the buckets, as the operator may desire.

Thelonger edges, a, of the buckets are'sharpened, as shown in Fig. 6, to avoid obstruction to the water-jet as it passes from one bucket to another in the wheels rotation, and the shorter edges, b, are shown directed nearly tangential to the side of the wheel, although the adhesion of the water to such edges secures the. discharge of thewater in an outward curve,

and thus avoids interference with the back of the succeeding bucket.

The water-jet is shown at d in Figs. 4 and 5 with the spent water at di passing beyond the edge of the guard into the chamber I, as described herein. Y a

I do not claim as new the discharge-chute or enlargement of the casing at its base, or as some would call it a spent-water pocket, as

it is an old and well-known device used by ThomasPattison, of Little York, California, in 1867, and by other makers of water-motors years previous tothat time, for the purpose of allowing a free discharge of the water and preventing the drag of back-water and choking of the wheel, which otherwise would fol- -1owand adhere to the wheel were it not for the enlargement of the case at the point indicated, which gives the water a chance to free itself from the wheel, and prevents a reaction of the water on the buckets and its being carried up by the buckets into thecircular portion of the case. Were the case unprovided with this chamber or pocket, as used by Mr. Pattison and others, to allow a free exit of the water at the'discharge-nozzle, it would, as can readily be seen, retard the motion of the wheel.

My invention differs from any previousconstruction,in actually requiring an enlargement of the casing at one side only to receive the water-discharge from the buckets, as at the chamber I, and in having a thin guard, as at J, applied between the edge of the wheel and said chamber,to confine the water to the latter when discharged therein, and to thereby prevent its contact with the succeeding buckets of the wheel.

The state of the art in this class of invention is shown in United States Patents Nos. 229,736, 249,274., 101,996, 266,922,116,405, En-' glishjPatent No. 964 of 187 6, and German Patent N 0. 3,896 of 1878. Such patents show that curved buckets arranged in different relations to the rim of the wheel are not new, and I therefore disclaim the said patents and limit my invention to the particular construction and arrangement of the buckets, and in a subordinate sense to their combination with the chamber I and the guard J.

Having thus set forth the nature of. my improvement and distinguished it from others, what I claim herein is- In a water-motor, the combination,'with a motor-wheel having parabolic bucket curved across the rim of the wheel and lateral openings between the bucket to admit a jet of water, of avertical casing providedat its bottom with an outlet and a nozzle inserted in the casing In testimony whereof I have hereunto set my hand in the presence of two subscribing 10 witnesses.
